Used in biomedical research to quantify leptin levels in porcine (pig) biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study metabolic regulation, appetite control, and energy balance in swine models. It is commonly applied in veterinary research, animal physiology studies, and agricultural science to investigate obesity, growth performance, and reproductive health. The assay provides a sensitive and specific measurement of porcine leptin, supporting experiments in nutrition, endocrinology, and metabolic disease modeling.
